An incremental encoder, often also referred to as an incremental rotary encoder or simply encoder, is an electromechanical device that provides motion information. It generates digital signals that represent the movement of a rotating or linear object. Every time the object moves, the encoder generates a digital signal known as an "increment," and the sum of these increments represents the overall movement of the object. In the context of bulk material sampling, an incremental encoder could be used in various applications, such as:
- Control of Sampling Devices: Incremental encoders could be employed to control and monitor the movement of sampling devices like automated scoops or drills.
- Conveyor Belt Monitoring: Incremental encoders could be utilized to monitor the speed and position of a conveyor belt used for the movement of bulk material.
- Level Measurement: In some cases, incremental encoders might be used in combination with other sensors to measure the level of a silo or another container containing bulk material.
It's important to note that while incremental encoders can provide valuable information about motion and position, they typically do not provide information about absolute position. For instance, when used to control a sampling device, it would likely be necessary to combine them with other sensors or control systems to ensure proper device positioning and accurate sampling.
